Bristol Palin has proved there is zero chance of a reconciliation between her and baby daddy Levi Johnston by dishing the dirt on her ex-beau in her new book.

In the soon-to-be released memoir entitled Not Afraid Of Life: My Journey So Far, the former Alaskan governor’s daughter refers to the father of her child as “the gnat” and claims that her relationship with him was full of “deception and disappointment.”

Bristol, 20, and Levi, 21, began dating when she was just 16-years-old and Bristol reveals that Levi “cheated on me as frequently as he sharpened his hockey skates.”

Ouch!

The single mother even describes what it was like to wake up in a tent the morning after she lost her virginity to Levi while on a camping trip.

Not long after, Bristol became pregnant at just 17, and gave birth to the couple’s son Tripp in late 2008.

The book, due for release next week, also details what it was like growing up in the Palin household.
